TECHNICAL FIELD

This application relates to the field of terminal technologies, and in particular, to a scrolling screenshot method and an electronic device.

BACKGROUND

In the prior art, a touchscreen 101 of an electronic device (for example, a mobile phone or a tablet computer) may display graphical user interfaces (GUI for short below) of various applications (App for short below). If a user needs to take a scrolling screenshot of a GUI currently displayed on the touchscreen 101, the user usually needs to first take a screenshot by using a preset gesture or by using a physical button, and then take a scrolling screenshot by tapping a scrolling screenshot control displayed on the touchscreen 101. Operations of the foregoing scrolling screenshot method are cumbersome, and consequently use efficiency of the electronic device is greatly reduced.

SUMMARY

To resolve the foregoing technical problem, this application provides a scrolling screenshot method and an electronic device, to improve use efficiency of the electronic device and also improve a capability of intelligent interaction between the electronic device and a user.

According to a first aspect, this application provides a scrolling screenshot method, the method may be implemented on an electronic device having a touchscreen, and the method may include: displaying a graphical user interface (GUI) of a first application on the touchscreen; detecting, by the electronic device, a screenshot operation performed by a user (for example, the user taps a control on the touchscreen 101); taking, by the electronic device, a screenshot of the GUI in response to the screenshot operation; displaying, on the touchscreen, a first preview image corresponding to an obtained first screenshot; detecting, by the electronic device, a first touch operation on the first preview image, where the first touch operation may be, for example, a downward swipe gesture made by a finger of the user on the first preview image; updating the first preview image to a second preview image in response to the first touch operation; and displaying the second preview image on the touchscreen. According to the technical solution in the foregoing embodiment, the electronic device may enable the user to take a scrolling screenshot by using a touch operation such as a swipe gesture on the preview image. This greatly improves scrolling screenshot efficiency of the electronic device, and also improves user experience.

In a possible implementation, the method further includes: detecting, by the electronic device, a second touch operation on the second preview image, where the second touch operation may be a touch and hold operation or a heavy press operation; displaying at least two controls on the touchscreen in response to the second touch operation, where the controls are used to perform different processing on a second screenshot corresponding to the second preview image; detecting, by the electronic device, a third touch operation on one of the controls; and sharing the second screenshot corresponding to the second preview image with a contact of a second application in response to the third touch operation. According to this implementation solution, the electronic device can help the user delete a scrolling screenshot, to improve processing efficiency of the scrolling screenshot.

In another possible implementation, the first preview image may be automatically updated based on a distance of the downward swipe gesture, and the updated first preview image (for example, the second preview image) is synchronously displayed. In this way, the electronic device can notify, by using a preview image or a GUI that is automatically updated on the touchscreen, the user of a real-time status of a scrolling screenshot when the user swipes in a scrolling screenshot gesture, to further guide the user to correctly take a screenshot, thereby improving scrolling screenshot efficiency of the electronic device, and further improving user experience.

In a possible implementation, the first preview image is a preview image of the first screenshot obtained by taking a screenshot of the displayed GUI, and the second preview image is a preview image of the second screenshot obtained by taking a scrolling screenshot of the first application.

In a possible implementation, the first touch operation is a downward swipe gesture on the first preview image; and the updating the first preview image to the second preview image in response to the first touch operation may specifically include: automatically updating, by the electronic device, the first preview image to the second preview image based on a swipe distance of the gesture.

In another possible implementation, the GUI of the first application is automatically updated and displayed when the first preview image is automatically updated to the second preview image. In this way, a display effect on the touchscreen may be used to notify the user of a scrolling screenshot process, to improve user experience.

In another possible implementation, the first screenshot corresponding to the first preview image is a screenshot of the currently displayed GUI, and the second screenshot corresponding to the second preview image not only includes the screenshot of the currently displayed GUI, but also includes a screenshot of content that is of the first application (for example, a weather application) and that is not displayed on the current GUI. Therefore, in terms of a display effect, a size of the first preview image may be less than a size of the second preview image. In this way, the user can easily identify whether a currently displayed preview image is a common screenshot or a scrolling screenshot. Certainly, in another possible implementation, although content of the first preview image is less than content of the second preview image, for uniform display effects, a size of the first preview image may alternatively be the same as a size of the second preview image.

According to a second aspect, an embodiment provides a scrolling screenshot method, the method may be implemented on an electronic device having a touchscreen, and the method includes: displaying a graphical user interface (GUI) of a first application on the touchscreen; detecting, by the electronic device, a screenshot operation; taking, by the electronic device, a screenshot of the GUI in response to the screenshot operation; displaying, by the electronic device in a first position of the touchscreen, a first preview image corresponding to an obtained first screenshot; detecting, by the electronic device, a first touch operation on the first preview image; and taking, by the electronic device, a scrolling screenshot of the GUI of the first application in response to the first touch operation. According to the technical solution in the foregoing embodiment, a gesture operation is performed on the first preview image, so that a scrolling screenshot can be taken very conveniently. In this way, efficiency of the electronic device is improved, and user experience is also improved.

In some possible implementations, the method may further include: displaying a second preview image on the touchscreen, where the second preview image is a preview image of a second screenshot corresponding to a scrolling screenshot.

In some other possible implementations, the first touch operation may be a downward swipe gesture on the first preview image; and the taking, by the electronic device, a scrolling screenshot of the GUI of the first application in response to the first touch operation may specifically include: automatically updating, by the electronic device, the displayed GUI of the first application on the touchscreen based on a swipe distance of the gesture.

In some possible implementations, the first preview image may be accordingly moved downward with swiping of the gesture with an unchanged size. In some possible implementations, the first preview image may be accordingly moved downward with swiping of the gesture, and the first preview image is automatically updated based on the swipe distance of the gesture.

In some possible implementations, when the gesture stops, the first preview image pops back and is displayed in the first position. In some other embodiments, when the gesture stops, the first preview image pops back and is displayed in the first position, the first preview image is automatically updated to the second preview image, and the second preview image is a preview image of the second screenshot captured based on the swipe distance of the gesture.

According to a third aspect, this application provides an electronic device, including a touchscreen, one or more processors, a memory, a plurality of applications, and one or programs. The processor is coupled to the memory, and the one or more programs are stored in the memory.

When making a call or sending voice information, the user may make a sound near the microphone 170C through the mouth of the user, to input a sound signal to the microphone 170C. At least one microphone 170C may be disposed in the electronic device 100. In some other embodiments, two microphones may be disposed in the electronic device 100, to collect a sound signal and implement a noise reduction function. In some other embodiments, three, four, or more microphones may alternatively be disposed in the electronic device 100, to collect a sound signal, implement noise reduction, and identify a sound source, so as to implement a directional recording function, and the like.

The headset jack 170D is configured to connect to a wired headset. The headset jack may be a USB interface, or may be a 3.5 mm open mobile terminal platform (open mobile terminal platform, OMTP) standard interface or cellular telecommunications industry association of the USA (cellular telecommunications industry association of the USA, CTIA) standard interface.

The pressure sensor 180A is configured to sense a pressure signal, and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A may be disposed on the display 194. There are many types of pressure sensors 180A, for example, a resistive pressure sensor, an inductive pressure sensor, and a capacitive pressure sensor. The capacitive pressure sensor may include at least two parallel plates made of a conductive material. When a force is applied to the pressure sensor 180A, capacitance between electrodes changes. The electronic device 100 determines pressure intensity based on the change of the capacitance. When a touch operation is performed on the display 194, the electronic device 100 detects intensity of the touch operation by using the pressure sensor 180A. The electronic device 100 may also calculate a touch location based on a detection signal of the pressure sensor 180A. In some embodiments, touch operations that are applied to a same touch position but have different touch operation strength may correspond to different operation instructions. For example, when a touch operation whose touch operation intensity is less than a first pressure threshold is performed on a messages application icon, an instruction for viewing an SMS message is performed. When a touch operation whose touch operation intensity is greater than or equal to the first pressure threshold is performed on the messages application icon, an instruction for creating a new SMS message is performed.

The gyro sensor 180B may be configured to determine a moving posture of the electronic device 100. In some embodiments, an angular velocity of the electronic device 100 around three axes (namely, axes x, y, and z) may be determined through the gyro sensor 180B. The gyro sensor 180B may be configured to implement image stabilization during photographing. For example, when the shutter is pressed, the gyro sensor 180B detects an angle at which the electronic device 100 jitters, calculates, based on the angle, a distance for which a lens module needs to compensate, and allows the lens to cancel the jitter of the electronic device 100 through reverse motion, to implement image stabilization. The gyro sensor 180B may also be used in a navigation scenario and a somatic game scenario.

The barometric pressure sensor 180C is configured to measure barometric pressure. In some embodiments, the electronic device 100 calculates an altitude by using the barometric pressure measured by the barometric pressure sensor 180C, to assist in positioning and navigation.

The magnetic sensor 180D includes a Hall sensor. The electronic device 100 may detect opening and closing of a flip cover through the magnetic sensor 180D. In some embodiments, when the electronic device 100 is a clamshell phone, the electronic device 100 may detect opening and closing of a flip cover based on the magnetic sensor 180D, to set a feature such as automatic unlocking through flipping based on a detected opening or closing state of the flip cover or a detected opening or closing state of the flip cover.

The acceleration sensor 180E may detect magnitude of accelerations in various directions (usually on three axes) of the electronic device 100, and may detect magnitude and a direction of the gravity when the electronic device 100 is still. The acceleration sensor 180E may be further configured to identify a posture of the electronic device, and is applied to an application such as switching between landscape orientation and portrait orientation or a pedometer.

The distance sensor 180F is configured to measure a distance. The electronic device 100 may measure the distance in an infrared or a laser manner. In some embodiments, in a photographing scenario, the electronic device 100 may measure a distance through the distance sensor 180F to implement quick focusing.

The optical proximity sensor 180G may include, for example, a light emitting diode (LED) and an optical detector such as a photodiode. The light emitting diode may be an infrared light emitting diode. The electronic device 100 emits infrared light through the light emitting diode. The electronic device 100 detects infrared reflected light from a nearby object through the photodiode. When sufficient reflected light is detected, it may be determined that there is an object near the electronic device 100. When insufficient reflected light is detected, the electronic device 100 may determine that there is no object near the electronic device 100. The electronic device 100 may detect, through the optical proximity sensor 180G, that the user holds the electronic device 100 close to an ear to make a call, to automatically perform screen-off for power saving. The optical proximity sensor 180G may also be used in a smart cover mode or a pocket mode to automatically perform screen unlocking or locking.

The ambient light sensor 180L is configured to sense ambient light luminance. The electronic device 100 may adaptively adjust luminance of the display 194 based on the sensed ambient light luminance. The ambient light sensor 180L may also be configured to automatically adjust white balance during photographing. The ambient light sensor 180L may further cooperate with the optical proximity sensor 180G to detect whether the electronic device 100 is in a pocket, to avoid an accidental touch.

The fingerprint sensor 180H is configured to collect a fingerprint. The electronic device 100 may implement fingerprint-based unlocking, application lock access, fingerprint-based photographing, fingerprint-based call answering, and the like by using a feature of the collected fingerprint.

The temperature sensor 180J is configured to detect a temperature. In some embodiments, the electronic device 100 executes a temperature processing policy by using the temperature detected by the temperature sensor 180J. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 lowers performance of a processor nearby the temperature sensor 180J, to reduce power consumption for thermal protection. In some other embodiments, when the temperature is less than another threshold, the electronic device 100 heats the battery 142 to prevent the electronic device 100 from being shut down abnormally because of a low temperature. In some other embodiments, when the temperature is less than still another threshold, the electronic device 100 boosts an output voltage of the battery 142 to avoid abnormal shutdown caused by a low temperature.

The touch sensor 180K is also referred to as a touch panel or a touch-sensitive surface. The touch sensor 180K may be disposed on the display 194, and the touch sensor 180K and the display 194 constitute a touchscreen 101 (not shown in FIG. 1 ). The touch sensor 180K is configured to detect a touch operation on or near the touch sensor 180K. The touch sensor may transfer the detected touch operation to the application processor to determine a type of the touch event. A visual output related to the touch operation may be provided through the display 194. In some other embodiments, the touch sensor 180K may alternatively be disposed on a surface of the electronic device 100 at a location different from that of the display 194.

The bone conduction sensor 180M may obtain a vibration signal. In some embodiments, the bone conduction sensor 180M may obtain a vibration signal of a vibration bone of a human vocal-cord part. The bone conduction sensor 180M may also contact a body pulse to receive a blood pressure beating signal. In some embodiments, the bone conduction sensor 180M may alternatively be disposed in the headset. The audio module 170 may obtain a speech signal through parsing based on the vibration signal that is of the vibration bone of the vocal-cord part and that is obtained by the bone conduction sensor 180M, to implement a speech function. The application processor may parse heart rate information based on the blood pressure beating signal obtained by the bone conduction sensor 180M, to implement a heart rate detection function.

The button 190 includes a power button, a volume button, and the like. The button may be a mechanical button, or may be a touch button. The electronic device 100 may receive a button input, and generate a button signal input related to a user setting and function control of the electronic device 100.

The motor 191 may generate a vibration prompt. The motor 191 may be configured to provide an incoming call vibration prompt and a touch vibration feedback. For example, touch operations performed on different applications (for example, a photographing application and an audio playing application) may correspond to different vibration feedback effects. The motor 191 may also correspond to different vibration feedback effects for touch operations performed on different areas of the display 194. Different application scenarios (for example, a time reminder scenario, an information receiving scenario, an alarm clock scenario, and a game scenario) may also correspond to different vibration feedback effects. A touch vibration feedback effect may alternatively be customized.

The indicator 192 may be an indicator light, which may be configured to indicate a charging status and a power change, or may be configured to indicate a message, a missed call, a notification, and the like.

The SIM card interface 195 is configured to be connected to a subscriber identity module (subscriber identity module, SIM). The SIM card may be inserted into the SIM card interface or detached from the SIM card interface, to implement contact with or separation from the electronic device 100. The electronic device 100 may support one or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 195 may support a nano-SIM card, a micro-SIM card, a SIM card, and the like. A plurality of cards may be inserted into one SIM card interface at the same time. The plurality of cards may be of a same type or different types. The SIM card interface 195 may further be compatible with different types of SIM cards. The SIM card interface 195 may further be compatible with an external storage card. The electronic device 100 interacts with a network by using the SIM card, to implement functions such as conversation and data communication. In some embodiments, the electronic device 100 uses an eSIM, namely, an embedded SIM card. The eSIM card may be embedded into the electronic device 100, and cannot be separated from the electronic device 100.

The following embodiments may be all implemented on an electronic device 100 (for example, a mobile phone or a tablet computer) having the foregoing structure.

For example, FIG. 2A and FIG. 2B show a series of graphical user interfaces (graphical user interface, GUI) displayed on the touchscreen 101 of the electronic device 100. These GUIs are on a home screen (Home Screen) of the electronic device. Usually, because a size of the touchscreen 101 of the electronic device is fixed, only a limited quantity of controls can be displayed on the touchscreen 101 of the electronic device. The control is a GUI element, and is a software component, which is included in an application and controls all data processed by the application and interaction related to the data. A user can interact with the control through direct manipulation (direct manipulation) to read or edit related information of the app. Usually, the control may include visual interface elements such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, and a widget. When there are an excessive quantity of controls on the home screen of the electronic device or when the user customizes arrangement of controls on the home screen, the home screen of the electronic device may be divided into a plurality of pages (Page). For example, a GUI shown in FIG. 2A may be referred to as a page 1 (Page 1) of the home screen, a GUI shown in FIG. 2B may be referred to as a page 2 (Page 2) of the home screen, and each page may include different controls. In an example of FIG. 2A, the GUI may be the page 1 of the home screen of the electronic device. The page 1 is displayed on the display 194 of the electronic device 100, and specifically includes a status bar 201, a collapsible navigation bar 202, a home screen indicator 203, and controls of various icons (for example, an app icon and a widget icon). The home screen indicator 203 is used to indicate, to a user, a specific page that is currently displayed. For example, the page 1 includes two rows and four columns of app icons, a weather widget, and date and time. When a finger of the user (a stylus or the like) touches a position on the touchscreen 101, in response to the touch event, the electronic device may open a graphical user interface of an app corresponding to an app icon or a widget. For example, in FIG. 2A, when the finger of the user lightly taps a position that is on the touchscreen 101 and that corresponds to a weather icon 205, a weather application is started, and a graphical user interface of the weather app is displayed on the touchscreen 101. It may be understood that, in some other embodiments, a dock bar may be further displayed on the display. The dock bar may include icons of frequently used apps, and these app icons may not change with a page of the home screen on the touchscreen 101.

In some other embodiments, the electronic device may further include a home button 204. The home button 204 may be a physical button, or may be a virtual button. The home button 204 is configured to receive a user instruction to return to the home screen from a currently displayed GUI, to display a specific subscreen of the home screen, so that the user can view the home screen at any time. The instruction may be specifically an operation instruction of pressing the home button 204 once by the user, or may be an operation instruction of successively pressing the home button 204 twice by the user within a short time, or may be an operation instruction of continuously pressing the home button 204 by the user within a preset time. In some other embodiments, a fingerprint recognizer 112 may be further integrated into the home button 204, so that a fingerprint is gathered and recognized when the home button 204 is pressed.

In the prior art, a user may simultaneously press the home button 204 and a power button to perform a screenshot operation, so as to obtain a screenshot of a displayed GUI related to an app. If the user needs to further share the screenshot, after completing the screenshot operation, the user needs to tap a sharing control displayed on the touchscreen 101, select an app, and select a contact from a contact list of the app. Then, the electronic device determines the contact based on selection of the user, and sends the screenshot to the contact through the app. It can be learned from the foregoing description that operations of a screenshot sharing solution in the prior art are excessively cumbersome, and consequently efficiency of interaction between the electronic device and the user is reduced, and user experience is also severely deteriorated.

The embodiments provide a screenshot sharing method, to greatly improve sharing efficiency of the electronic device, and also improve user experience. The following describes the technical solution of the embodiments with reference to FIG. 3A to FIG. 3G to resolve the foregoing technical problem.

FIG. 2A shows the first page of the home screen of the electronic device 100, and there is the icon 205 of the weather app on the first page. In response to a touch operation performed by a user on the icon 205, a GUI 301 of the weather app is displayed on the touchscreen 101, as shown in FIG. 3A. The GUI displays weather information within one week in Shenzhen. The weather information includes temperatures (a highest temperature and a lowest temperature) and specific weather conditions. When the user wants to share the weather information with another user, the user may perform a screenshot operation on the GUI displayed on the touchscreen 101. For example, the screenshot operation may be that the user simultaneously presses a power button 206 and the home button 204 (as shown in FIG. 2A). Alternatively, the screenshot operation may be that the user taps a control on the touchscreen 101, and this is more quick and convenient. For another example, the screenshot operation may be based on a gesture made by the user on the touchscreen 101. When the electronic device 100 determines that the gesture is a preset gesture, the electronic device determines that the user is performing the screenshot operation. In response to the screenshot operation, the electronic device 100 executes a screenshot instruction corresponding to the screenshot operation, and displays a preview image of an obtained screenshot on the touchscreen 101.

Specifically, in some embodiments, after receiving the screenshot operation performed by the user, the electronic device 100 may invoke a surface.screenshot( ) function to take a screenshot of a GUI displayed on the display 194. It may be understood that the electronic device 100 may alternatively take a screenshot in another manner. This is not limited in this embodiment. It may be understood that the obtained screenshot may be in various image formats, for example, a JPG format and a PNG format. As shown in FIG. 3B, a GUI 301 of the weather application is displayed on the touchscreen 101, and a preview image 302 of the screenshot is displayed in the lower left of the touchscreen 101. The preview image 302 may be displayed in the lower left of the touchscreen 101 with a specific scale. Certainly, the preview image may alternatively be displayed in the lower right of the touchscreen 101. In some embodiments, the preview image 302 may be displayed near two frames of the touchscreen 101 that are perpendicular to each other. To be specific, the preview image 302 is close to two frames of the display but do not coincide with the two frames. In some other embodiments, the preview image 302 may alternatively coincide with the two frames.

In some embodiments, to share the obtained screenshot with another user more conveniently and more quickly, the electronic device 100 may display the preview image 302 of the screenshot in a position that is on the touchscreen 101 and that can be touched by a finger of the user. For example, after the electronic device 100 executes the screenshot instruction, the electronic device 100 may first determine a one-hand holding posture of the user, and then display, based on the determined posture, the preview image of the screenshot in a position corresponding to the posture. For example, after executing the screenshot instruction, a mobile phone first determines a posture that the user holds the mobile phone with the left hand, and the mobile phone displays, in the lower left of the touchscreen 101 based on the posture, the preview image of the screenshot obtained by executing the screenshot instruction. In this way, the user can conveniently perform a subsequent operation such as sharing on the preview image when the user holds the electronic device with the left hand, to improve user experience. For another example, after executing the screenshot instruction, the mobile phone first determines a posture that the user holds the mobile phone with the right hand, and the mobile phone displays the preview image of the obtained screenshot in the lower right of the touchscreen 101 based on the posture. It should be noted that, how the electronic device 100 determines the one-hand holding posture of the user is the prior art in the art, and details are not described herein.

In some embodiments, after the electronic device 100 detects a touch (for example, tap) operation performed by the user on the preview image 302, in response to the touch operation, the touchscreen 101 may display a GUI for editing the screenshot corresponding to the preview image 302. The GUI may include various editing controls, for example, graphics controls such as a cropping control, a rotation control, a brightness control, and a color temperature control.

In some embodiments, as shown in FIG. 3B, after detecting that a finger 303 of the user makes an upward swipe gesture 304 on the touchscreen 101, the electronic device 100 displays a function menu 305 on the touchscreen 101 in response to the gesture. The function menu 305 may include a sharing control. After detecting a touch operation performed by the user on the sharing control, the electronic device 100 may display a submenu 308 on the touchscreen 101 in response to the touch operation, and may no longer display the original function menu 305, as shown in FIG. 3C. The submenu 308 includes some applications (Apps) that may be used to share the screenshot, for example, WeChat, Skype, Facebook, and QQ. For example, after the user touches an icon of WeChat, a contact list of WeChat may be displayed on the touchscreen 101, so that the user can conveniently select a contact with which the user wants to share the screenshot. After the electronic device 100 detects the touch operation of selecting a contact by the user, the electronic device 100 may send the screenshot 302 to the selected contact through WeChat in response to the touch operation. According to the technical solution in the foregoing embodiment, the electronic device 100 can conveniently share the screenshot with another user (for example, a contact or a friend of another app). Therefore, the foregoing technical solution improves screenshot sharing efficiency of the electronic device, and also improves user experience.

In some embodiments, after detecting that the finger 303 of the user makes a downward swipe gesture 307 on the touchscreen 101, the electronic device 100 may display a function menu 306 on the touchscreen 101 in response to the gesture, as shown in FIG. 3D. The function menu 306 includes a scrolling screenshot control. After the electronic device 100 detects a touch operation performed by the user on the control in response to the touch operation, the electronic device executes a scrolling screenshot instruction, and displays a preview image 313 of an obtained screenshot on the touchscreen 101, as shown in FIG. 3E. In some embodiments, because content captured in a scrolling screenshot is more than content captured in a common screenshot, the preview image 313 may be slightly larger or longer than the preview image. In this way, the user can conveniently distinguish between screenshot types (the common screenshot or the scrolling screenshot).

In some embodiments, when displaying the preview image 313 on the touchscreen 101, the electronic device 100 may save the screenshot corresponding to the preview image 313 in an album, and enable a prompt box 314 to pop up on the touchscreen 101 to prompt the user. According to the technical solution in this embodiment, the electronic device 100 may automatically take a scrolling screenshot based on a gesture of the user, and automatically save the obtained screenshot in the album. In this way, screenshot processing efficiency is improved, and user experience is further improved.

In some other embodiments, the electronic device 100 may further perform different corresponding operations on the screenshot based on different gestures of the user. For example, as shown in FIG. 3F, after executing the screenshot instruction based on the screenshot operation performed by the user, the electronic device 100 displays the preview image 302 of the obtained screen shot on the touchscreen 101. After the electronic device 100 detects a selection (for example, heavy press or touch and hold) operation performed by the finger 303 of the user on the preview image 302, in response to the selection operation, the electronic device 100 may move the preview image 302 from the lower left of the touchscreen 101 to the middle of the touchscreen 101, and display more controls, as shown in FIG. 3G. In FIG. 3G, the GUI 301 of the weather app is blurred, the preview image 302 is displayed in the middle of the touchscreen 101, and controls 309 to 312 are displayed. The control 309 is used to delete a screenshot, the control 310 is used to save the screenshot in the album, the control 311 is used to share the screenshot with a WeChat contact, and the control 312 is used to take a scrolling screenshot.

For example, as shown in FIG. 3G, when detecting a leftward swipe gesture made by the user on the preview image 302, the electronic device 100 executes a screenshot deletion instruction in response to the gesture. When detecting a rightward swipe gesture made by the user on the preview image 302, the electronic device 100 executes a screenshot saving instruction in response to the gesture. When detecting an upward swipe gesture made by the user on the preview image 302, the electronic device 100 executes a screenshot sharing instruction in response to the gesture. When detecting a downward swipe gesture made by the user on the preview image 302, the electronic device 100 executes a scrolling screenshot instruction in response to the gesture. In this way, the user can perform different operations on the screenshot based on different gestures, to improve screenshot processing efficiency of the electronic device, and further improve user experience.

It may be understood that, in some other embodiments, in FIG. 3G, the finger 303 of the user may alternatively tap one of the controls to execute a corresponding instruction, and does not need to make an upward swipe gesture, a downward swipe gesture, or the like. For example, after the finger 303 of the user taps the control 309, the screenshot corresponding to the preview image 302 is deleted in response to the tap operation, and the GUI 301 of the weather app is displayed on the touchscreen 101 again. For another example, after the finger 303 of the user taps the control 312, the electronic device 100 performs a scrolling screenshot operation in response to the tap operation. This control-based manner can improve accuracy of screenshot processing performed by the user, and avoid a false operation on a screenshot that is caused by an incorrect gesture.

In some other embodiments, based on FIG. 3F, after the electronic device 100 detects a selection (for example, heavy press or touch and hold) operation performed by the finger 303 of the user on the preview image 302, in response to the selection operation, the electronic device 100 may enable the preview image 302 to be in an intermediate state. The intermediate state is used to prompt the user to perform a next operation on the preview image 302, for example, the user may make a swipe gesture on the preview image. The intermediate state may be presented on the touchscreen 101 as follows: The preview image 302 is displayed with a larger size, or a display effect of the preview image 302 is shaking, or a display effect of the preview image 302 is floating. In some other embodiments, in addition to the foregoing presentation, the intermediate state may be further presented as follows: The controls 309 to 312 are displayed around the preview image 302, to further prompt the user to perform a next operation.

A display effect used to indicate that the preview image 302 is in the intermediate state is presented on the touchscreen 101, so that an operation guide can be provided for the user very intuitively. The operation guide can guide the user to continue to perform a subsequent operation on the preview image 302 when the finger of the user does not leave the touchscreen 101 after the selection operation. In this way, an operation time of the user is reduced, and user experience is further improved.

For example, when the finger of the user does not leave the touchscreen 101 after the selection operation such as a touch and hold operation, the user may continue to make a downward swipe gesture. The electronic device 100 may perform a scrolling screenshot operation in response to the downward swipe gesture. Alternatively, when the finger of the user does not leave the touchscreen 101 after the selection operation such as a touch and hold operation, the user may continue to make an upward swipe gesture. The electronic device 100 may perform a screenshot sharing operation in response to the upward swipe gesture. According to the technical solution in the foregoing embodiment, the electronic device 100 may perform next processing on a screenshot in response to a selection operation performed by the user on a preview image of the screenshot. In this way, screenshot processing efficiency of the electronic device 100 is improved, and user experience is further improved.

In some other embodiments, based on FIG. 3F, after the electronic device 100 detects a selection (for example, press or touch and hold) operation performed by the finger 303 of the user on the preview image 302, if the finger 303 of the user further makes a swipe gesture, the electronic device 100 may perform different processing on the preview image 302 in response to the swipe gesture. In other words, in this embodiment, the electronic device 100 may not need to enable the preview image 302 to be in the intermediate state. Only when the electronic device 100 detects the swipe gesture (for example, the gesture 304 or 307) made by the user after detecting the selection operation such as a press operation or a touch and hold operation on the preview image 302, the electronic device 100 performs corresponding processing on the preview image 302 in response to the swipe gesture. For specific processing, refer to the foregoing embodiment. Details are not described herein again. FIG. 2A shows the first page of the home screen of the electronic device 100, and there is the icon 205 of the weather app on the first page. In response to a touch operation performed by a user on the icon 205, a GUI 401 of the weather app is displayed on the touchscreen 101, as shown in FIG. 4A. The GUI displays weather information within one week in Shenzhen. The weather information includes temperatures (a highest temperature and a lowest temperature) and specific weather conditions. When the electronic device 100 detects an upward swipe gesture 404 of a finger 403 of the user in the GUI, in response to the gesture 404, the GUI of the weather app also scrolls with swiping of the gesture, and displays more weather information. As shown in FIG. 4B, the GUI displays weather information that is not displayed in FIG. 4A, for example, today's detailed weather conditions: a sunrise time, a sunset time, a wind speed, and an apparent temperature.

When the user wants to take a screenshot to obtain all weather information in FIG. 4A and FIG. 4B, the user usually needs to first take a common screenshot (the screenshot is the content displayed in the GUI 401 in FIG. 4A) by using a preset gesture or by using a physical button, and then performs a scrolling screenshot operation by tapping a control displayed on the touchscreen 101. Alternatively, the user may first take a screenshot to obtain the content in FIG. 4A, then take a screenshot to obtain the content in FIG. 4B, and next combine the two screenshots into one scrolling screenshot (which may also be referred to as a long screenshot) by using an algorithm. It can be learned from the foregoing description that operations of the two scrolling screenshot methods are cumbersome and greatly reduce use efficiency of the electronic device.

To resolve the foregoing technical problem, the embodiments provide a scrolling screenshot method, to greatly improve scrolling screenshot efficiency of the electronic device 100, and also improve user experience. A specific implementation solution is described in detail in the following embodiments.

As shown in FIG. 4C, after the user performs a screenshot operation on the GUI 401, the electronic device 100 executes a screenshot instruction in response to the screenshot operation, and displays a preview image 402 of a screenshot on the touchscreen 101. The preview image 402 is a preview image that is of the GUI 401 currently displayed on the touchscreen 101 and that is captured by the electronic device 100. After the finger 403 of the user taps the preview image 402, a GUI for editing the screenshot corresponding to the preview image 402 may be displayed on the touchscreen 101. The GUI may include various editing controls, for example, graphics controls such as a cropping control, a rotation control, a brightness control, and a color temperature control.

In some embodiments, as shown in FIG. 4C, after the electronic device 100 detects a heavy press selection operation or a touch and hold selection operation performed by the finger 403 of the user on the preview image 402, the electronic device 100 further detects a downward swipe gesture 405 made by the user. In response to the gesture 405, the electronic device 100 performs a scrolling screenshot operation, and displays a preview image 403 of a captured scrolling screenshot on the touchscreen 101, as shown in FIG. 4F. In FIG. 4F, the finger 403 of the user has been lifted from the touchscreen 101, and the preview image 403 of the scrolling screenshot is displayed on the touchscreen. In some other embodiments, in response to that the finger 403 of the user lifts from the touchscreen 101, the electronic device 100 may automatically save the obtained scrolling screenshot (namely, a long screenshot), and may display a prompt box 404 on the touchscreen. The prompt box 404 is used to inform the user that the scrolling screenshot has been saved in an album. FIG. 4H is a schematic diagram of a screenshot obtained after the electronic device 100 performs a scrolling screenshot operation. Content in the screenshot may be all weather information displayed in FIG. 4A and FIG. 4B. In some other embodiments, as shown in FIG. 4H, the electronic device may display an indicator 413 in the screenshot, and the indicator 413 is used to indicate screenshot software through which the screenshot is taken.

It should be noted that, in the foregoing embodiment, if the electronic device 100 does not detect a heavy press selection operation or a touch and hold selection operation performed by the user on the preview image 402, but detects a gesture 405 made by the user, the electronic device 100 may hide the preview image 402 in response to the gesture 405. In this case, the GUI 401 of the weather app is still displayed on the touchscreen 101, and the preview image 402 is no longer displayed, as shown in FIG. 4A. In other words, only when the electronic device 100 detects the heavy press selection operation or the touch and hold selection operation, the gesture 405 indicates that the user wants to perform a scrolling screenshot operation, and the electronic device performs the scrolling screenshot operation in response to the gesture 405. In this way, a problem of incorrectly taking a scrolling screenshot that is caused by a false operation of the user is avoided, thereby improving user experience.

In some other embodiments, when the electronic device 100 detects that the finger of the user makes a downward swipe gesture 405 on the preview image 402, in response to the gesture 405, the electronic device 100 performs a scrolling screenshot operation, and displays a thumbnail preview image 403 of a captured scrolling screenshot on the touchscreen 101. In this embodiment, the user does not need to first touch and hold or heavily press the preview image 402, but taps the preview image 402 and then drags the preview image 402 down. In this way, the electronic device can accordingly perform the scrolling screenshot operation, and update the preview image 402 to a preview image 411.

In some other embodiments, after the finger 403 of the user performs a heavy press selection operation or a touch and hold selection operation on the preview image 402, in response to the selection operation, the electronic device 100 may enable the preview image 402 to be in an intermediate state. The intermediate state is used to prompt the user to perform a next operation on the preview image 302, for example, the user may make a swipe gesture on the preview image. The intermediate state may be presented on the touchscreen 101 as follows: The preview image 402 is displayed with a larger size, or a display effect of the preview image 402 is shaking, or a display effect of the preview image 402 is floating. In some other embodiments, in addition to the foregoing presentation, the intermediate state may be further presented as follows: The controls 309 to 312 are displayed around the preview image 302, to further prompt the user to perform a next operation. In this way, use efficiency of the electronic device 100 is further improved, and user experience is further improved. A display effect used to indicate that the preview image 402 is in the intermediate state is presented on the touchscreen 101, so that the electronic device 100 can provide an operation guide for the user very intuitively. The operation guide can guide the user to continue to perform a subsequent operation on the preview image 402 when the finger of the user does not leave the touchscreen 101 after the selection operation. In this way, an operation time of the user is reduced, and user experience is further improved.

In some other embodiments, the electronic device 100 may accordingly capture, based on a swipe distance of the gesture 405 on the touchscreen 101, a part or all of content of the weather app that is not displayed in FIG. 4A, and may dynamically display preview images of different screenshots on the touchscreen 101. A larger swipe distance of the gesture 405 indicates more captured content, and vice versa.

For example, as shown in FIG. 4C, the electronic device 100 detects the downward swipe gesture 405 of the user on the preview image 402. The electronic device 100 starts to perform a scrolling screenshot operation on the weather app in response to the gesture 405. As shown in FIG. 4D, when the gesture 405 swipes from a position A on the touchscreen to a position B on the touchscreen 101, a preview image 410 of an obtained screenshot is displayed on the touchscreen 101. This indicates that a scrolling screenshot corresponding to a swipe distance AB from the position A to the position B is a screenshot represented by the preview image 410. Specifically, in the preview image 410, content 410-1 at the bottom of the obtained screenshot can be seen. A screenshot including content from a captured status bar to the content 410-1 at the bottom is the screenshot corresponding to the swipe distance from the position A to the position B of the gesture 405.

As shown in FIG. 4E, after the gesture 405 swipes from a position A to a position B, and continues to swipe to a position C, a preview image 411 of an obtained screenshot is displayed on the touchscreen. This indicates that a scrolling screenshot corresponding to a swipe distance AC from the position A to the position C is a screenshot represented by the preview image 411. Specifically, in the preview image 411, content 411-1 at the bottom of the obtained screenshot can be seen. A screenshot including content from a captured status bar to the content 411-1 at the bottom is the screenshot corresponding to the swipe distance from the position A to the position C of the gesture 405. In this case, when the user continues to perform a swipe operation, for example, swipes from the position C to a position D (not shown in the figure), in response to a touch operation that the gesture 405 swipes from the position C to the position D, a prompt box is displayed on the touchscreen 101. The prompt box is used to inform the user that there is no extra content for screenshot currently. In other words, because screenshots for all content of the weather app have been taken, the electronic device 100 cannot obtain a corresponding screenshot based on a swipe distance from the position C to the position D. In this way, the prompt box may be used to prompt the user, so that user experience of taking a scrolling screenshot can be further improved. It may be understood that the position A, the position B, and the position C may be all located in each preview image, or may be all located outside each preview image.

In some other embodiments, in a process in which the user makes the downward swipe gesture 405, a preview image of a screenshot that is displayed on the touchscreen 101 may be automatically updated and displayed. In some other embodiments, the preview image is automatically updated with the swipe distance of the gesture 405, and the GUI of the weather app may also be automatically updated and displayed with the swipe distance of the gesture 405. For example, as shown in FIG. 4D, if the electronic device detects that the gesture 405 swipes from the position A to the position B, the preview image 402 is updated to the preview image 410, screenshot content corresponding to the swipe distance AB is added to the preview image 410, and an updated GUI of the weather app is displayed on the touchscreen 101 and a weather condition 409 is included. Content of the weather condition 409 is the same as content of the weather condition 410-1 in the preview image 410, that is, the GUI of the weather app is automatically updated. Likewise, after the gesture 405 swipes from the position A to the position B, and continues to swipe to a position C, the preview image 410 is updated to the preview image 411, screenshot content corresponding to a swipe distance BC is added to the preview image 411, and an updated GUI of the weather app is displayed on the touchscreen 101 and a weather condition 411 is included. Content of the weather condition 411 is the same as content of the weather condition 411-1 in the preview image 411, that is, the GUI of the weather app is automatically updated again. It should be understood that, as long as the swipe distance is changed (for example, is increased or decreased), the GUI of the weather app is automatically updated accordingly, and the preview image is also automatically updated and displayed. According to the foregoing technical solution, the electronic device 100 can prompt, by using a preview image or a GUI that is automatically updated on the touchscreen, the user with a real-time status of a scrolling screenshot when the gesture made by the user to take a scrolling screenshot swipes, to further guide the user to correctly take a screenshot, improve scrolling screenshot efficiency of the electronic device, and further improve user experience.

In some other embodiments, the user alternatively makes the downward swipe gesture 405 in an opposite direction (for example, upward). In this case, the preview image may also be automatically updated. For example, as shown in FIG. 4E, the gesture 405 may swipe from the position A to the position C. In this case, the preview image 411 is displayed on the touchscreen 101. Then, the user makes an upward swipe gesture 415 (not shown in the figure) when the finger of the user does not leave the touchscreen 101. The gesture 415 swipes upward from the position C to the position B. In this case, the preview image 411 may be automatically updated to the preview image 410, and this indicates that content in a scrolling screenshot is accordingly reduced. The preview image 410 is displayed on the touchscreen 101, as shown in FIG. 4D.

In some other embodiments, when the finger 403 of the user makes the downward swipe gesture 405 on the preview image 402, a size and content of the preview image 402 may remain unchanged, and the preview image 402 may be moved downward as the finger 403 of the user drags the preview image 402 down, as shown in FIG. 4I. In addition, when the gesture 405 is in progress, the graphical user interface of the weather app that is displayed on the touchscreen 101 may also scroll upward accordingly. In this way, updated weather information that is not displayed previously is displayed on the touchscreen 101. For example, the weather information 409 is currently displayed, as shown in FIG. 4I. After the finger of the user is lifted and leaves the touchscreen 101, the operation indicates that the user has ended the gesture 405. Therefore, in response to the lifting operation, the preview image 402 on the touchscreen 101 may be moved to an original position by using an upward pop-back animation effect, as shown in FIG. 4J. The position may be a position in which the preview image 402 is located when the finger 403 of the user does not touch the preview image 402, for example, a position in which the preview image 402 is located in FIG. 4C. In some other embodiments, after the preview image 402 pops back to the original position, the preview image 402 may be automatically updated to the preview image 410 or 411. In other words, a position of the preview image 410 may be the same as the position of the preview image 402.

It should be noted that, in this embodiment, the selection operation and the gesture 405 may be operations continuously performed by the user. For example, the user first performs the heavy press selection operation or the touch and hold selection operation, and then performs the downward swipe gesture 405 when the finger 403 does not leave the touchscreen 101.

In some other embodiments, as shown in FIG. 4C, after detecting a selection (for example, heavy press or touch and hold) operation performed by the user on the preview image 402, the electronic device 100 may display a GUI in FIG. 4G in response to the selection operation. In the GUI, the preview image is displayed with a floating effect, and controls 405 to 408 are displayed. When the user makes a leftward/rightward/upward/downward swipe gesture on the preview image 402 (or 410, 411, 413, or the like), in response to the gesture, the electronic device 100 may perform different processing on the screenshot corresponding to the preview image.

It should be noted that FIG. 3A to FIG. 3G, FIG. 4A to FIG. 4J, and the like are schematic diagrams used to explain and describe the technical solutions in the foregoing related embodiments, and numbers and arrangement sequences of the diagrams cannot indicate operation sequences of a series of graphical user interfaces in the embodiments. The numbers and arrangement sequences of the foregoing accompanying drawings may also be in another form.

With reference to the foregoing embodiments and the corresponding accompanying drawings, an embodiment provides a scrolling screenshot method. The method may be implemented on the electronic device 100 (for example, a mobile phone or a tablet computer) having the structure shown in FIG. 1 . As shown in FIG. 5 , the method may include the following steps.

Step S501: The electronic device displays a GUI of a first application on a touchscreen. The first app may be the weather application in the foregoing embodiment, and the GUI of the first app may be shown in FIG. 3A, FIG. 3B, FIG. 4A, or FIG. 4B.

Step S502: The electronic device detects a screenshot operation performed by a user. For example, as shown in FIG. 2A, the screenshot operation may be that the user simultaneously presses the power button 206 and the home button 204. Alternatively, the screenshot operation may be that the user taps a control on the touchscreen 101, and this is more quick and convenient. For another example, the screenshot operation may be based on a gesture made by the user on the touchscreen 101. When the electronic device 100 determines that the gesture is a preset gesture, the electronic device determines that the user is performing the screenshot operation. How to perform the screenshot operation is not limited in this embodiment.

Step S503: The electronic device takes a screenshot of the GUI in response to the screenshot operation, and displays, on the touchscreen, a first preview image corresponding to an obtained first screenshot. The first preview image may be the preview image 402 shown in FIG. 4C.

Step S504: The electronic device detects a first touch operation on the first preview image.

In some embodiments, the first touch operation may be a downward swipe gesture made by a finger of the user on the first preview image. In some other embodiments, the first touch operation may alternatively be as follows: A finger of the user performs a touch and hold selection operation or a heavy press selection operation on the first preview image, and then performs a downward swipe gesture without leaving the touchscreen. For example, as shown in FIG. 4C, the first touch operation may be that the finger 403 of the user performs a heavy press selection operation on the preview image 402, and then makes the downward swipe gesture 405 without leaving the touchscreen 101.

Step S505: Update the first preview image to a second preview image in response to the first touch operation, and display the second preview image on the touchscreen.

For example, when the electronic device detects the selection operation, if the electronic device receives a swipe gesture (for example, the downward swipe gesture 405) made by the user on the preview image 402, the electronic device starts to take a scrolling screenshot in response to the swipe gesture. As described in the foregoing embodiment, the electronic device may accordingly capture screenshots of different content based on a swipe distance of the swipe gesture (for example, the gesture 405) on the touchscreen, and may dynamically display preview images of the different screenshots on the touchscreen. For example, the first preview image is a preview image corresponding to the first screenshot captured based on the screenshot operation performed by the user, and the second preview image is a preview image of a second screenshot captured based on the first touch operation.

In some embodiments, the first touch operation may be a downward swipe gesture. In this case, the electronic device may capture, based on a swipe distance of the gesture, a screenshot including different content, and display, on the touchscreen, the second preview image corresponding to the screenshot. That is, the first preview image is updated to the second preview image for display.

In some embodiments, both the first preview image and the second preview image may correspond to the first application. In other words, the two preview images are different preview images that are displayed and that are obtained by taking screenshots of the first application.

According to the technical solution in the foregoing embodiment, the electronic device may enable the user to take a scrolling screenshot by using a touch operation such as a swipe gesture on a preview image. This greatly improves scrolling screenshot efficiency of the electronic device, and also improves user experience.

In some other embodiments, the first preview image may be automatically updated to the second preview image based on a distance of the touch operation such as the swipe gesture in step S504, and the second preview image is displayed on the touchscreen. In some other embodiments, when the first preview image is automatically updated to the second preview image, the GUI of the first application is automatically updated and displayed.

In some embodiments, the first screenshot corresponding to the first preview image is a screenshot of the currently displayed GUI, and the second screenshot corresponding to the second preview image not only includes the screenshot of the currently displayed GUI, but also includes a screenshot of content that is of the first application (for example, a weather application) and that is not displayed on the current GUI. Therefore, in terms of a display effect, a size of the first preview image may be less than a size of the second preview image. In this way, the user can easily identify whether a currently displayed preview image is a common screenshot or a scrolling screenshot. Certainly, in some other embodiments, although content of the first preview image is less than content of the second preview image, for uniform display effects, a size of the first preview image may alternatively be the same as a size of the second preview image.

In some other embodiments, the scrolling screenshot method may further include the following steps.

Step S506: The electronic device detects a second touch operation on the second preview image, where the second touch operation may be a touch and hold operation or a heavy press operation.

Step S507: Display at least two controls on the touchscreen in response to the second touch operation, where the controls are used to perform different processing on the second screenshot corresponding to the second preview image.

For example, these controls may be the controls 405 to 408 in FIG. 4G. In FIG. 4G, when detecting a touch operation performed by the user on the control 414, the electronic device 100 deletes the screenshot in response to the touch operation. When detecting a touch operation performed by the user on the control 406, the electronic device 100 saves the screenshot in response to the operation. When detecting a touch operation performed by the user on the control 407, the electronic device 100 shares the screenshot with a WeChat contact in response to the operation. When detecting a touch operation performed by the user on the control 408, in response to the operation, the electronic device 100 takes a scrolling screenshot of the weather app displayed on the touchscreen 101. In this way, the user can perform different operations on the second screenshot based on different controls, to improve screenshot processing efficiency of the electronic device, and further improve user experience.

Step S508: The electronic device detects a third touch operation on one of the controls.

Step S509: Share the second screenshot corresponding to the second preview image with a contact of a second application in response to the third touch operation.

For example, the control may be the control 407 in FIG. 4G, and the control 407 is used to share the second screenshot corresponding to the preview image with a WeChat contact.

In some other embodiments, as shown in FIG. 4G, when detecting a leftward swipe gesture made by the user on the preview image 410, the electronic device 100 deletes the screenshot in response to the gesture. When detecting a rightward swipe gesture made by the user on the preview image 410, the electronic device 100 saves the screenshot in response to the gesture. When detecting an upward swipe gesture made by the user on the preview image 410, the electronic device 100 shares the screenshot with a WeChat contact in response to the gesture. When detecting a downward swipe gesture made by the user on the preview image 410, in response to the operation, the electronic device 100 takes a scrolling screenshot of the weather app displayed on the touchscreen 101. In this way, the user can perform different operations on the screenshot based on different gestures, to improve screenshot processing efficiency of the electronic device.

It may be understood that the gesture in the foregoing embodiment, for example, the gesture 304, 307, 405, or 415, may be a swipe gesture on (or for) any position on the touchscreen 101, or may be a swipe gesture on a preview image (for example, the preview image 302) of a screenshot. In the latter case, only a swipe gesture (for example, the gesture 304 or 307) on the preview image 302 can trigger display of the function menu 305 or the function menu 305 on the touchscreen 101. In some embodiments, the swipe gesture on (or for) the preview image 302 may be specifically as follows: The finger 303 of the user touches the displayed preview image 302, and then makes an upward slide gesture or a downward slide gesture without leaving the touchscreen 101. In some other embodiments, the gesture on the preview image 302 may alternatively be as follows: The finger 303 of the user heavily presses the preview image 302, and then makes an upward swipe gesture or a downward swipe gesture without leaving the touchscreen 101. Certainly, the foregoing merely describes an example of a gesture on the preview image 302. In some other embodiments, the gesture may alternatively be another type of gesture. The gesture is not limited in this embodiment.

As shown in FIG. 7 , an embodiment provides a scrolling screenshot method. The method may be implemented on an electronic device 100 having a touchscreen, and includes the following steps.

Step S701: Display a graphical user interface (GUI) of a first application on the touchscreen.

Step S702: The electronic device detects a screenshot operation.

Step S703: The electronic device takes a screenshot of the GUI in response to the screenshot operation.

Step S704: The electronic device displays, in a first position of the touchscreen, a first preview image corresponding to an obtained first screenshot.

Step S705: The electronic device detects a first touch operation on the first preview image.

Step S706: The electronic device takes a scrolling screenshot of the GUI of the first application in response to the first touch operation.

According to the technical solution in the foregoing embodiment, a gesture operation is performed on the first preview image, so that a scrolling screenshot can be taken very conveniently. In this way, efficiency of the electronic device is improved, and user experience is also improved.

In some other embodiments, the foregoing method may further include the following step:

Step S707: Display a second preview image on the touchscreen, where the second preview image is a preview image of a second screenshot corresponding to a scrolling screenshot.

In some other embodiments, the first touch operation may be a downward swipe gesture on the first preview image.

In this case, that the electronic device takes a scrolling screenshot of the GUI of the first application in response to the first touch operation may specifically include: automatically updating, by the electronic device, the displayed GUI of the first application on the touchscreen based on a swipe distance of the gesture.

In some embodiments, the first preview image may be accordingly moved downward with swiping of the gesture with an unchanged size. In some other embodiments, the first preview image may be accordingly moved downward with swiping of the gesture, and the first preview image is automatically updated based on the swipe distance of the gesture.

In some embodiments, when the gesture stops, the first preview image pops back and is displayed in the first position. In some other embodiments, when the gesture stops, the first preview image pops back and is displayed in the first position, and the first preview image is automatically updated to the second preview image. The second preview image is a preview image of the second screenshot captured based on the swipe distance of the gesture.
